(Peer review + Similarity) COMPARISON OF INVERTER TYPES FOR HOME APPLIANCE USING PUSH-PULL AMPLIFIER (Experimental Inverter Types at Engineering Laboratory)

This paper deals with a comparison of inverter types and develops
a system to provide pure sine wave ac voltage. The ac voltage is utilized to
drive the compressor ac split. The assembled inverter problem is a square
waveform, power losses, torque, efficiency, and a lag behind in terms of
performance reliability. The push-pull amplifiers technic is proposed to produce sine wave output from dc input. The output result shows that an
experimental pure sin wave obtains a frequency of 50.05 Hz, V max 13.49
Volt, V min -14.49 volt, and duty cycle 50.1%. the assembled inverter has a
frequency is 37.87 Hz, V max 11.88 Volt, V min 13.09 volt, and a duty
cycle is 50 %. A modified 3-phase inverter attains frequency 50.05 Hz, V
max 15.71 Volt, V min -16.11 Volt, and the duty cycle is 50.5 %. The
frequency, v max, v min, and duty cycle are bigger than an assembled
inverter, then the modified 3-phase inverter has small harmonic distortion.
The comparison of inverter types gives information for home appliances.
